D.H.
Go to Home Depot, get the Home Defense spray.I have used this for over 10 yrs. It really works like it says it does. First you saturate you house, all around the inside first(the window seals, base boards, under cabinets, and wherever you feel you need to spray), then go to the outside, spray all of your entrance areas, all walkways, garage areas, and all around the edge of the house. This will not hurt you pets, there is little to no smell, and it really works, Do this twice a month until you feel comfortable enough to do once a month and then once every two to three months. This is guarenteed to work.God Bless
